Ok I hope I am not breaking any rules here but I just heard something and couldn't get a real answer when I googled it.

My ex's aunt and I were talking and she was shocked he could pass a drug test. She said it was all that pickle juice he drank. What??? She was told that it would clean out your system or whatever and you could pass a urine test.

Now, I lived with him about a year and yes every now and then he might drink it (yuck) but not a whole lot and there was no certain day he did it on, but honestly I didn't pay attention to it.

a long time ago (at least 20 years) that was the case, it was the vinegar that did the trick. however, drug tests have gotten a lot more sophisticated in recent years and this old trick is no longer effective.

Drug tests are so sensitive in this day and age that no amount of anything will work. I recently did 30 hours of alcohol classes and 2 9people were there for failing drug tests. They've both tried everything to pass and nothing has ever worked.

A)No, it won't work.
B)Some places will call an "inconclusive" screen a fail if they have any excuse at all to believe the sample was in any way altered or diluted.

Bottom line is that there is only one reliable way to pass a urine test and that's to avoid drugs for which you're subject to screening..... and to be very careful about legit. meds and over-the-counter treatments.
When in doubt, tell your doctor or pharmacist that you're subject to drug tests and ask if what you're prescribed mimics any illicit drug.
